Disk Drive Controller
The system drive controller is an important part of system performance. In most modern boards your drive controller will run off of the PCI-e bus. The PCI-e bus performance can be affected by poor trace layout as well as many other design choices that show up on different boards.
For testing we use Sisoft's Sandra and Everest.
HDD performance was a little off for the SATA II controller, but SATA 3.0 and USB 3.0 performance is right on the money.
Everest shows us a little better performance, but it is still not up there with what we have seen form P55 based boards.
